The number of students enrolled at hill school decreased by 120 students over an 8-year period what was the average decrease in student enrollment per year

Answer:

1

Step-by-step explanation:

6 - 4x = 6x - 8x+ 4

6 - 4x = -2x + 4

-4x + 2x = 4 - 6

-2x = -2

x = -2/-2

x = 1

Given:

Area of rectangle = [tex]15\dfrac{7}{16}[/tex] sq. feet.

Width of the mirror = [tex]3\dfrac{1}{4}[/tex] feet.

To find:

Whether it will fit on the wall whose length is 5 foot.

Solution:

We know that, area of a rectangle is

[tex]Area=length\times width[/tex]

[tex]\dfrac{Area}{width}=length[/tex]

Substituting the given values, we get

[tex]Length=\dfrac{15\dfrac{7}{16}}{3\dfrac{1}{4}}[/tex]

[tex]Length=\dfrac{\dfrac{15\times 16+7}{16}}{\dfrac{3\times 4+1}{4}}[/tex]

[tex]Length=\dfrac{\dfrac{240+7}{16}}{\dfrac{12+1}{4}}[/tex]

[tex]Length=\dfrac{\dfrac{247}{16}}{\dfrac{13}{4}}[/tex]

[tex]Length=\dfrac{247}{16}\times \dfrac{4}{13}[/tex]

[tex]Length=4.75 [/tex]

So, length of mirror is 4.75 feet which is less than 5 feet.

Therefore, the mirror will fit on the wall.

Answer:

f(-x)=-f(x)

So, Function f is odd

Option C is correct.

Step-by-step explanation:

Which statement is true about function f, which is shown in the graph?

f(x)= -8x⁵+ 4x³+5x?

Function is even if f(-x)= f(x)

and function is odd if f(-x)=-f(x)

Putting x=-x and finding f(-x)

f(-x)=-8(-x)^5+4(-x)^3+5(-x)

f(-x)=-8(-x^5)+4(-x^3)-5x

f(-x)=+8x^5-4x^3-5x

f(-x)=-(-8x^5+4x^3+5x)

f(-x)=-f(x)

So, Function f is odd

Option C is correct.

The function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = -8x⁵+ 4x³+5x

Plug x → -x

f(-x) = -8(-x)⁵+ 4(-x)³+5(-x)

f(-x) = 8x⁵- 4x³-5x

f(-x) = -( -8x⁵+ 4x³+5x)

f(-x) = -f(x) (condition for odd function)

Thus, the function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.

Answer:

Slope = 2

Step-by-step explanation:

To find slope, you use the formula [tex]\frac{y1-y2}{x1-x2}[/tex]

[tex]\frac{4-12}{2-6} = \frac{-8}{-4} = 2[/tex]

So the slope = 2

2n is the same as twice a number added by itself and 3n is the same as 3 times a number then it has minus 10

Answer: No it is not proportional

All direct proportion equations are in the form y = kx, for some fixed number k.

If we had y = 17x, without the 2 at the end, then it would be in the form y = kx with k = 17. In other words, y = 17x is a direct proportion equation.

The 2 at the end is why we don't have a direct proportion equation. The y intercept must be 0. All direct proportion equations go through the origin.

Answer: it should be x

Step by step explanation: the x table changes at a rate of 6 when the y table changes at a rate of 4

Answer: [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.

Step-by-step explanation:

We assume that quantity of flour is proportional to butter.

Given : The recipe calls of [tex]1\dfrac14[/tex] cups of  flour  and [tex]\dfrac12[/tex] stick of butter.

Let [tex]x_1=1\dfrac14=\dfrac{5}{4}[/tex]      [tex]y_1=\dfrac{1}{2}[/tex]

For [tex]y_2=3[/tex] , we will find [tex]x_2[/tex] by using formula of direct proportion: [tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]

[tex]\dfrac{\dfrac{5}{4}}{\dfrac12}=\dfrac{x_3}{3}\\\\\Rightarrow\ \dfrac{5}{2}=\dfrac{x_3}{3}\\\\\Rightarrow\ x_3=\dfrac{5}{2}\times3= \dfrac{15}2=7\dfrac12[/tex]

Hence, [tex]7\dfrac12[/tex] cups of flour is required for 3 sticks of butter.

15/2 cups of flour!

2nd box: 5

3rd box: 8

4th box: 11

5th box: 14

Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.

2x2x2x2x2x2 is 64

Step-by-step explanation:

The value of the equations is S = 64

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 2⁶

On simplifying the equation , we get

A = 64

Therefore , the value of A = 64

Hence , the equation is A = 64

Answer:

Step-by-step explanation:

You should set this up as an y = mx + b equation. Since 300 is her final number, that will be your y value. She started with 100, so that will be your b value. 20 is the number related to the variable you don't know so that will be your m.

300 = 20x + 100

-100            -100

200 = 20x

divide both sides by 20

10 = x

Answer:

C

Step-by-step explanation:

Since XY = XZ = 6, then the triangle is isosceles.

The base angles are therefore congruent, that is

∠ Y = ∠ Z = 70°

The sum of the 3 angles in the triangle = 180°, thus

∠ X = 180° - (70 + 70)° = 180° - 140° = 40° → C
